Description: Float level switch is a simple structure, easy to use level control devices, it does not provide power, no complicated circuit, it has a smaller volume than the general mechanical switch,long working life and other advantages. As long as the material selection is correct in shape, and the nature of any liquid or pressure, temperature can be used, which in the shipbuilding industry, generating equipment, petrochemical, food industry, water treatment equipment, dyeing and finishing industry, hydraulic machinery, etc. have been widely applications. How it works: An important level sensor magnetic reed switch and the float composed of magnetic material inside the float, set up one or more magnetic reed switch in a closed non-magnetic metal pipe or plastic pipe, and then the catheter through a or more with magnetic float, and double loop control with fixed float and reed switch in the relevant position, the float rises or falls with the liquid, use inside the ball close to the beginning of the reed contact, resulting in open and closed action, for level control or direction (when float near the reed switch is turned on switch off when you leave). Specification: Product Name: Water Level Sensor Cable Length: 37cm or 14.6" Float Ball Size(Approx): 10 x 24mm or 0.39" x 0.94" (DxH) Thread Dia(Approx): 11.5mm or 0.453" Hex Nut Size(Approx): 19mm or 0.748" Bottom Clip Dia(Approx): 20.5mm or 0.8" Total Size: 55 x 35mm or 2.16" x 1.38" (LxW) x Water Level Sensor White PP Right Angle Float Switch Max Contact Rating:10W Max Switching Voltage: 100V DC Max Switching Current: 0.5A Max Breakdown Voltage: 220V DC Max Carry Current: 1.0A Max Contact Resistance: 100m Temperature Rating: -10 - and60 C or and85 C Float Ball Material: PP Float Body Material: PP. A float switch is a device used to sense the level of liquid within a for tank. The switch may actuate a pump, an indicator, an alarm, or other device.
